<u><em>Answer</em></u>

$x=\frac{11}{3}$

<u><em>Explanation</em></u>

Based on the given conditions, formulate:: $y=3$

Substitute $y=3$ into $y=-6x+25$ :: $3=-6x+25$

Rearrange variables to the left side of the equation: $6x=25-3$

Calculate the sum or difference: $6x=22$

Divide both sides of the equation by the coefficient of variable: $x=\frac{22}{6}$

Cross out the common factor: $x=\frac{11}{3}$

What is the volume of a right cone having a base diameter of 10 cm and a height of 9 cm?

lions [1.4K]

Answer:

volume = (1/3)(area of base)(height)

area of base = pi * radius2 = pi * (10/2)2 = pi * 52 = 25pi cm2

volume = (1/3)( 25pi )( 9 ) cm3

volume = 75pi cm3

volume ≈ 236 cm3

A leg of a triangle is 2 units and the hypotenuse is 4 units, what's the length of the other leg of the triangle?

lana [24]

The equation that you would use would be 4^2-2^2=a^2 (a^2+b^2=c^2). you would have to square the numbers and subtract. then your answer should be the square root of 12. So the answer technically would be C, but it worded kinda weird. It should say "the square root of 12". Hope this helped.

A bus with kids and a truck with their bags started moving from the school to the camp at the same time. The speed of the bus wa

natta225 [31]

Answer:

1 hour

Step-by-step explanation:

The distance covered by each of the two vehicle can be written as

$d=vt$

where

d is the distance covered

v is the speed of the vehicle

t is the time elapsed

For the bus, the speed is

$v_b = 60 mph$

So the distance covered by the bus in a time t is

$d=60t$ (1)

The kids in the bus took 3 hours to reach the camp,

t = 3 h

So the distance between the school and the camp is:

$d=(60)(3)=180 mi$

For the truck, the speed is

$v_t=45 mph$

So the distance covered by the truck in a time t is

$d=45t$ (2)

Since the distance to cover is 180 miles, the time taken by the truck is

$t=\frac{d}{45}=\frac{180}{45}=4 h$

And so, the truck arrives

$\Delta t = t_t - t_b = 4 h - 3 h = 1 h$

1 hour after the bus.

A line on the coordinate plane passes through the points (7, -5) and (3, 11). A line that is perpendicular to the first line pas

yulyashka [42]

Slope of the line passing through (7,-5) and (3,11) =
$\frac{11 - ( - 5)}{3 - 7}$
= -4

As two lines are perpendicular to each other, so when their slopes are multiply by each other, the answer will be -1

so the slope of the line passing through (-3,-9) and (5,n) will be
$\frac{1}{4}$
So will will get a formula below
$\frac{n - ( - 9)}{5 - ( - 3)} = \frac{1}{4}$
and the answer will be n=
$- 7$
